Embodiment 1

[0057] Embodiment 1: A kind of waterborne polyurethane super wear-resistant topcoat, each component raw material and corresponding weight parts thereof are as shown in Table 1, and prepare and obtain through the following steps:

[0058] Step 1, high-temperature calcination, calcining the wear-resistant ball powder corresponding to the weight part in a high-temperature reaction furnace at 200°C for 1 hour, and then screening with a 100-mesh sieve to obtain pretreated wear-resistant ball powder;

[0059] Step 2, mix the materials, mix the corresponding parts by weight of water-based polyurethane resin AH-1618, leveling agent BYK346, defoamer BYK024, defoamer Tego901W and polyurethane rheological agent SN612NC in a mixing tank with a disperser and mix evenly. The rotating speed of the disperser is 300rpm, stirring for 20min, then adding deionized water in corresponding parts by weight, maintaining the original rotating speed, stirring for 5min, to obtain the mixed material;

Abstract

The invention discloses waterborne polyurethane super wear-resistant finish paint and a preparation process thereof, and relates to the technical field of preparation of finish paint, aiming at solving the problem that the finish paint is poorer in wear resistance, so that local damage is easily caused in a using process. The finish paint is prepared from a component A and a component B, wherein the component A is prepared from the following raw materials: 50-60 parts of waterborne polyurethane resin AH-1618, 12-18 parts of polyurethane color paste, 0.8-1.2 parts of a leveling agent BYK346, 0.3-0.5 part of an aqueous leveling agent BYK333, 0.3-0.6 part of a polyurethane rheological agent SN612NC, 0.3-0.5 part of a defoaming agent BYK024, 0.08-0.1 part of a defoaming agent Tego901W, 0.8-1.5parts of rutile titanium dioxide, 8-10 parts of wear-resistant ball powder, 0.8-1.5 parts of an aqueous scratch-resistant agent, 1.2-1.6 parts of propylene glycol methyl ether and 12-18 parts of deionized water; the component B is prepared from 95-100 parts of a polyurethane curing agent; the ratio of parts by weight of the component A to parts by weight of the components B is equal to (4-6) to 1. The waterborne polyurethane super wear-resistant finish paint has good wear resistance after being cured.

Description

technical field [0001] The invention relates to the technical field of topcoat preparation, more specifically, it relates to a waterborne polyurethane super wear-resistant topcoat and a preparation process thereof. Background technique [0002] Topcoat is the final coating of painting, and it is the last layer applied in building wall decoration. The overall effect after decoration is reflected through this layer. [0003] In the Chinese invention patent whose notification number is CN107955506A, a white finish paint set and its preparation method and application are disclosed. The white finish paint set includes: the first white finish paint component, and the first white finish paint component contains: 40 ~65% by weight zero-VOC aqueous hydroxy acrylic dispersion, 2-5% by weight coalescent, 0.2-0.5% by weight defoamer, 0.4-1.5% by weight dispersant, 0.2-0.8% by weight wetting agent, 0.2-1% by weight leveling agent, 20-30% by weight titanium dioxide, 0.2-1% by weight thic...
